The crash happened early Sunday morning on Chicago's West Side in the Humboldt Park neighborhood. Family members spoke with ABC7 about the victim and his younger brother, who was badly injured and hospitalized at Illinois Masonic Hospital.
Police say they have not questioned or arrested anyone who may have been driving the pickup truck involved in the accident.
Eduardo Perez, 25, of Berwyn died in the fatal hit-and-run accident on Sunday morning. He is survived by his wife and two children under the age of 2.
Perez lived in the home of his uncle, Ruben Barreto, in Berwyn.
"He was a great man, a great father, took care of his kids. Always with his kids. He worked. They [Eduardo's children] were always with them. He was basically the babysitter for them, and now these kids aren't going to have no babysitter," said Barreto, victim's uncle.
Police confirm that three vehicles were involved in the crash in the 1600-block of North Kostner. According to police, a silver four-door pickup truck rear-ended a 2005 Hyundai Elantra, and then rear-ended a Toyota Camry, which Perez was driving. He was pronounced dead on the scene.
"He loved to play pool, that was his favorite sport. I just hope they catch what this guy is and they can pay his thing in there, you know, for what he did," said Barreto.
A passenger in the Camry, Eduardo Perez's 17-year-old brother, was taken to Advocate Illinois Masonic Hospital, where his uncle says he was fighting for his life.
"Right now, he's pretty much fighting. He's bleeding from the brain. Right now he's up, stuff like that, but he's still bleeding and they're still taking a few more scans of his brain to see what's going on," said Barreto.
On Monday afternoon, Baretto said his nephew is improving and is hoping he will be released from the hospital on Monday evening.
